How to reduce memory consumption of uBO? It keeps crashing

[XCanG]

I have an issue that is somewhat consistent, but not appear very often (once in a week). uBO keeps consuming a lot of RAM until it reaches about 10 GB and then extension crashed because "Out of memory". I can keep track of the memory in Google Chrome internal task manager (Shift+Esc). To me it feels like uBO keeps some kind of logs or something that accumulate over time and the more it blocks, the faster it crashes. I find out that using site like YouTube that have a lot of ads (like 500-1000 per tab) make this accumulation of RAM faster.

I don't know what else to add, but I didn't find any options that can reduce RAM usage or could clear current RAM.

Specs:

• Windows 10 x64
• Google Chrome v126.0.6478.127
• uBlock Origin 1.59.0

The crash was for extension, but it can be reloaded again in extension menu. But it's process, that run extension uses this amount of RAM. While I use other extensions and they do not consume this much RAM and don't crash.

Google Chrome v126.0.0.0.0

Is this really the exact version of your Google Chrome? If not, can you provide the exact version?

I also check Console tab in devtools and find that there are 570 errors of same kind:

a recent example where an other extension - Bitwarden password manager affected uBO badly

Ohh, didn't know that, I also use Bitwarden.

This is fixed in dev build with gorhill/uBlock@1b464f7.

No clue. You could try the dev build to see if this changes something.
